Title: Bidirectional coupling of electrical systems
IPC: H03K19/018
Filed: 1978-01-20
Abstract: A circuit arrangement which can be disposed at the interface of two electrical systems (I, II), for example integrated semiconductor systems, with different operating voltages in such a way that DC voltage signals can pass through the interface in both directions and a transformation takes place from one operating voltage to the respective other operating voltage. The circuit arrangement is made up of two DC hybrid circuits (a1, b1, e1, a2, b2, e2) connected back-to-back. The two-way arm (b1, b2) of each hybrid circuit is connected to the input/output of one of the two electrical systems (I, II). The output arm (a1, a2) of each hybrid circuit is connected to the control input of a controllable switching component (T1, T2) whose input is connected to a voltage source (T1-60V; T2-5V) and whose output is connected to the input arm (e1, e2) of the respective other hybrid circuit. The rated voltage of the voltage sources in each case corresponds to the input/output voltage of the system which is connected to the output of the controllable switching component concerned. Transistors, relays or opto-electronic couplers serve as controllable switching components (T1, T2). <IMAGE>

Filed: 1967-01-17
Abstract: 1,174,662. Shift register. GENERAL ELECTRIC CO. 17 Jan., 1967 [28 March, 1966], No. 2415/67. Heading G4P. Each stage of a shift register comprises two non-bi-stable gates 1a, 1b, Fig. 2 (also Fig. 1, not shown) and a trigger FF1. One pair of control inputs 7a, 7b of the gates is fed by inverse outputs from the previous stage, and the other pair 6a, 6b is normally maintained at a subambient pressure. Thus, normally the power jet of each gate is biased to atmosphere 8a, 8b. Shifting is effected by applying positive shift pulses to inputs 6a, 6b, but the shift pulses are arranged to be of smaller amplitude than a " one " input to inputs 7a and 7b, from the previous stage, and hence, when the subambient bias is replaced by a shift pulse the power jet of one of the gates is switched, via channel 9a, 9b to switch the trigger FF1, which, being bi-stable, remains in the condition to which it was switched after the controlling input ceases.

Title: Process for the sublimation of substances in a fluidised bed sublimer
IPC: B01D7/00
Filed: 1956-01-25
Abstract: <PICT:0815604/III/1> Solid material is sublimed by mixing with an inert solid in vessel B, introducing gas at the bottom of the vessel to fluidize the solids and carry the material to be sublimed to condenser C, and withdrawing inert solid free from material to be sublimed from the base of the fluidized bed.  Sublimed solid is removed from condenser C at D and gas is recirculated through pump E, heat-exchanger F and reheater G, back to vessel B.  Inert solid withdrawn from vessel B is used as a fluidized bed in heat-exchanger F to heat the circulating gas and is then treated at H to remove sublimation residue and returns to the top of vessel B.  In an example, 1,5-diamino-anthraquinone is sublimed, using sand as the inert solid and nitrogen as the carrier gas.ALSO:1,5-Diamino-anthraquinone is purified by sublimation in the presence of a bed of sand fluidized with nitrogen (see Group III). The sublimate is collected in a condenser and sand free from sublimable material is withdrawn from the bottom of the bed, unsublimable residue is removed and the sand recycled to the top of the bed together with the material to be sublimed.
